Troximon aurantiacum, T. glaucum, Mertensia sibirica, Cam- 

 panula rotundifolia, Aconitum cohimbianum, etc., being observed. 

 The mollusca were equally characteristic, including Patula 

 Cooperi, Conulus fulvus, Limncea humilis, Pupa blandi and 

 others. The insects corresponded; on September 26th, I saw 

 Vanessa antiopa; on September 30th, Vespa maculata; and at 

 various times species of Grapta, Colias, Lithobius, Geophilus, 

 etc. A marten was shot by one of our party, and a Pulex found 

 parasitic upon it. 



On September 30th we moved a few miles further down the 

 valley, and at this camp I took a wasp, Vespa arenaria Fab. ; 

 two beetles, Platycertis sepressus Lee. $ (under a log) and Ne- 

 crophorus vespilloides Hbst. (flying by day), and a Vanessa Mil- 

 bertii. I have also a note of Hippodami-a $-signaia Kirb. on 

 Surface Creek, and Pterostidms protradtis 'L&o.. , Delta County, 

 the locality not exactly noted. P. protraclus is recorded in the 

 Wheeler Report from Fort Garland and the Roaring Fork, and 

 so appears to be of wide distribution in Colorado, although I did 

 not find it in Custer County. Colorado, as a whole, seems to 

 contain comparatively few species of Pterostichus (though two 

 or three are 'abundant), but plenty of Amara, thus: —

In September, I crossed the northern border of the county 

 close to the Mam Mountains, and traveled by way of Buzzard 

 Creek and Plateau Creek to the Grand Mesa. This region is 

 mid-alpine, but descending Plateau Creek we should soon meet 

 with sub-alpine features, and even near Eagalite, where we 

 camped, they were becoming quite marked. It will be convenient 

 to group the notes imder three districts: 



(i) Buzzard Creek District. — The divide between North 

 Mam Creek and Buzzard Creek is not so high but that the Scrub 

 Oak grows there, being ordinary mid-alpine. Elk {Cervus cana- 

 densis) and black-tailed deer ( C. macrotis) were observed on the 

 Mam Mountains. At our camp near the foot of i-he Mam Moun-
